| May 7, 2021 at 15:42 | comment | added | user22279 | lat/lon is a very intuitive system to define a point on the earth, used for navigation since many centuries. Simpler mathematically but less intuitive for humans are origin vectors. Computers use cartesian coordinates and convert back and forth for human interaction. It's fun playing with these things when rendering planets ;-) As @hobbs pointed out, a meridian is just a great circle. en.wikipedia.org/wiki/Great_circle and en.wikipedia.org/wiki/Great-circle_distance | |

That's where you would get to if you draw a line parallel to the north south axis of the poles, instead of straight through the earth's core. It's not an antipode. | |
| May 7, 2021 at 9:59 | comment | added | Stack Exchange Supports Israel | @B.ClayShannon Now imagine picking up the Earth, and turning it so that Monterey is on the equator (Monterey moves south). What happens on the opposite side from Monterey? It moves in the opposite direction i.e. north, because that's how rotating a sphere works | |
| May 7, 2021 at 1:16 | comment | added | hobbs | (to help visualize that: the lines of longitude are the great circles that pass through the two poles. You could imagine picking up that network of lines, and putting it back down so that one of the points of convergence lands in Monterey. Now find the other one.) | |
| May 7, 2021 at 1:13 | comment | added | hobbs | @B.ClayShannon using the ordinary definition, when you go "halfway around the world" it doesn't matter what direction you set out in. All of the great circle paths through a given point converge on one other point, which is the antipode, and the distance along any of those paths to the antipode is half the circumference of the Earth :) | |

| May 6, 2021 at 9:59 | comment | added | user22279 | Are you looking for the antipode of a point on earth's surface ? Would it help to take the equator as reference instead of a pole and poke from Monterey right through the earth's center until you come out the other side ? en.wikipedia.org/wiki/Antipodes | |
